title: Endocardial late potentials during sinus rhythm define the re-entry circuit of ventricular tachycardia in arrhythmogenic right ventricular cardiomyopathy.
abstract: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an inherited cardiomyopathy characterized by progressive fibro-fatty replacement of the right ventricular myocardium. We report a case where mapping of endocardial potentials during sinus rhythm identified the re-entry circuit of a recurrent ventricular tachycardia in a patient with ARVC. The tachycardia was subsequently ablated successfully.
